must have reached the necessary operating tempera-
ture. The operating temperature is reached after the
warm-up time. The warm-up time starts when the device
is switched on.
Procedure
Switch on the device.
t
Wait until the operating temperature is reached
t
(warm-up time see Chapter "15.7 Warm-up Time",
page 38).
If a weighing process is carried out on a con-
formity-assessed device during the warm-up
time: The weight value is marked as invalid.

To level the device: Bring the air bubble of the level
t
indicator into the middle of the circular marking. To
do so, turn the leveling feet to the left or right.
Check that the device is standing on 4 leveling feet
t
and the support foot (1) is not in contact with the
setup surface.
8.4 Overview of Calibration and
Adjustment
During calibration, a calibration weight is used to
determine the deviation of the displayed value from the
actual value. The subsequent adjustment eliminates this
deviation.
We recommend regular calibration and adjustment:
— Daily, every time the device is switched on
— After every leveling
— After changing the ambient conditions (temperature,
humidity, or air pressure)
— After setting the device up at a new installation site
